Output:
10
Program 2:
<?php // Create a new ImagickDraw object $draw = new ImagickDraw(); // Create a new imagick object $imagick = new Imagick(); // Create a image on imagick object $imagick->newImage(800, 250, 'white'); // Create a new ImagickDraw object $draw = new ImagickDraw(); // Set the stroke color $draw->setStrokeColor('green'); // Set the stroke opacity $draw->setStrokeOpacity(0.6); // Set the fill color $draw->setFillColor('white'); // Set the stroke width $draw->setStrokeWidth(10); // Set the stroke Line Join $draw->setStrokeLineJoin(Imagick::LINEJOIN_MITER); // Set the stroke miter limit $draw->setStrokeMiterLimit(0); // Create a polygon $draw->polygon([ ['x' => 100, 'y' => 60], ['x' => 60, 'y' => 80], ['x' => 400, 'y' => 100] ]); // Set the font size $draw->setFontSize(20); // Decrease the stroke width so that text can be printed $draw->setStrokeWidth(1); // Print the text $draw->annotation(450, 100, 'The strokeMiterLimit here is ' . $draw->getStrokeMiterLimit()); // Set the stroke width back to 10 $draw->setStrokeWidth(10); // Set the stroke miter limit $draw->setStrokeMiterLimit(40); // Create a polygon $draw->polygon([ ['x' => 100, 'y' => 160], ['x' => 60, 'y' => 180], ['x' => 400, 'y' => 180] ]); // Decrease the stroke width so that text can be printed $draw->setStrokeWidth(1); // Print the text $draw->annotation(450, 180, 'The strokeMiterLimit here is ' . $draw->getStrokeMiterLimit()); // Render the draw commands $imagick->drawImage($draw); // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
